Basic physics

1. The problem statement, all variables and given/known data
How do I find the elongation of a spring when just given K=119 N/m, mass of the wooden block it is attached to=4.17kg and the densty of the wooden block = 695 kg/m^3.

2. Relevant equations
I do not know what equation to use.

3. The attempt at a solution
I have not been able to make an attempt because I do not know what equation to start off with.

Well im trying to find the elongation of the spring. So the correct equation is F=-kx???
Does that mean that I change it to solve for x?? x= F/-k
I do not kno how to find the force for the equation if I only have the mass and density of the wooden block the string is attached to. I am completely lost!
